STYLOGRAPHIC FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 275,912', dated April1'7, 1883.

Application led October 11, 188i. (No model.)

To all whom it may concern:

Be it known that l, JOHN HOLLAND, of the city of Cincinnati, county ofHamilton, State of Ohio, have invented certain new and usefulImprovements in Stylographic Fountain- Pens, of which the following is aspecification.

This invention relates to that class of writing-instruments in which thehandle serves as areservoirforink,theowofwhichiscontrolled by a needleprotruding through the writingpoint.

The objects of the invention are to provide a convenient means foradjust-ing the needle, and to insure a regular tlow of the ink when inuse.

The invention will be first fully described, referring to theaccompanying drawings, and particularly pointed out in the claims.

Figure l is a central vertical sectional view of the lower part of a pencontaining my improvements, the upper portion ofthe pen,which is commonand in general use, being shown in elevation. Fig. 2 is a centralvertical section of the needle-holder and its attachments. Fig. 3 is aperspective view ofthe needle and needie-holder.

Similar reference-letters indicate the same parts wherever they occur.

The holder A, air-tube B, point-section D, and vent-cap C are the sameas those in common use, and need no particular description here.

The point-section D has an internal screwthread to receive a thread uponthe needleholder E. The needle-holder is a tube, preferably of hardrubber, the upper end being open to receive the lower end of theair-tube B. The lower end of needle-holder E has a central perforation,through which the spindle or needle F protrudes. The needle has anenlargement or head within the tube E, between which and the screw-pluggis compressed a spiral spring,f. On the exterior of tube E, near thetop, is a collar, e', which is screwthreaded to engage the screw-threadwithin the point-section. By this means the needle is adjusted in thewriting-point. A burr, e, at the top of the holder E is for conveniencein turning the holder to protrude or retract the needle with relation tot'ne writing point.

Through the collar c and burr c are channels e2, to admit ink from thehandle A into the point-section D around the diminished lower end of theneedle-holder E. Transverse perforations I in the lower end ofneedle-holder E admit air t'rom tube B to the point-section D. By thismeans I am enabled to admit the air nearer the writing-point, whichinsures a more uniform flow of ink in use and prevents leakage when notin use. By my arrangement of the adjustable needle-holder in thepointsection I am enabled to readily adjust the needle with relation tothe writing with great nicety, and in case the needle sticks or clogswith ink it is easily freed by moving it back and forth through itsholder' E. While I have shown a screw-joint between the point-sectionand needle-holder, as it allows of more accurately adjusting theneedle-valve, a frictionA joint could be made to answer the purpose.rlhe holder E is separable by a joint at h, to afford access to thescrew-plug g to loosen or compress the springf when desired.

It will be seen that in my pen the needlepoint is readily adjustable tosuit the hand of the writer For instance, if the writers habit is tohold a pen perpendicularly, or nearly so, the point is retracted, so asto leave but a small portion of it protruding through the writingpoint;or, if it is desired to write with the holder much inclined, the needleis protruded farther to insure the opening of the valve. Again, somewriters desire a hard77 point, like apencil, in writing, while othersrequire some elasticity or spring, like the common pen. My pen can bereadily adapted to the hand of either. If the hard touch is required,the plug g is unscrewed to slacken the springf, so that the needle willbe pushed back in writing without appreciable pressure. If the plug g isdriven down and the spring compressed hard between the head of theneedle and' plug, the pressure ofthe spring will be plainly felt inwriting.

I claiml. The combination, substantially as before set forth, of thehandle A, the point-section D, and the holder E, carrying thespring-pressed needle, and extending above the point-section, to afforda convenient means to adjust the nee- I, and the air-tube B, theperforated lower v end of which extends within the needle-holder.

die with relation to the writing-point when the point-section isremoved.
